Notes

FULL-ROW TOKEN SWEEP, never a sample (CAV-050): every rendered row's flag column was read and the DISTINCT token set recorded. 40 of 40 rows read and CONFIRMED ON TWO DIFFERENTLY-VARIED FETCHES: https://www.tcdb.com/Checklist.cfm/sid/154910/2016-17-Panini-Grand-Reserve-Rookie-Cornerstones-Marble?sort=0 and https://www.tcdb.com/ViewSet.cfm/sid/154910/2016-17-Panini-Grand-Reserve-Rookie-Cornerstones-Marble . tcdb states "Total Cards: 40", numbers 101-140 contiguous. DISTINCT TOKEN SET {AU, MEM, SN8, SN10}: thirty-nine rows read SN10 and card 134 Dario Saric reads "AU, MEM, SN8" on both endpoints, the second quoting the string and the player back when asked for that card specifically. ONE ROW IN FORTY, and it is the whole difference between an honest UNKNOWN and a confident wrong 10 - which is also what Panini's own unqualified "Marble (numbered to 10)" (https://blog.paniniamerica.net/the-panini-america-quality-control-gallery-2016-17-grand-reserve-basketball/) would have produced. UNKNOWN/UNKNOWN per EXTRACTION_SPEC 2.3; census in G-012. CHANNEL: hobby with basis `sourced-presence`, NOT exclusivity. The statement is PRODUCT-LEVEL - Panini's own blog says "each hobby box of 2017 Grand Reserve Basketball" (https://blog.paniniamerica.net/the-panini-america-quality-control-gallery-2016-17-grand-reserve-basketball/), cardboardconnection says "three hits per hobby box" and gives one single configuration, "8 cards per pack, 3 packs per box, 8 boxes per case" (https://www.cardboardconnection.com/2016-17-panini-grand-reserve-basketball), and blowoutbuzz gives one SRP for the same pack (https://blowoutbuzz.wordpress.com/2017/05/16/first-buzz-2016-17-panini-grand-reserve-basketball-cards/). No source consulted names a retail, blaster, mega or international SKU for this product, and no source claims exclusivity, so presence is the strongest claim the evidence supports and it is applied at product level rather than per tier. See G-010.
